Keep an updated image of the standalone on laptop, update it via chroot, |
| 13 |
and sync back to the standalone. |
| 14 |
|
| 15 |
ie: |
| 16 |
|
| 17 |
fix CFLAGS="-march=..." in etc/make.conf to reflect your cpu in |
| 18 |
standalone pc. |
| 19 |
|
| 20 |
rsync the standalone file system (excluding the virtual dirs, and /dev |
| 21 |
and tmp dirs) to a <standalone> directory on laptop's disk or to an |
| 22 |
external (usb) disk. |
| 23 |
|
| 24 |
mount appropriate dirs in <standalone> |
| 25 |
|
| 26 |
Better make an init script (like /etc/init.d/standalone), so you can |
| 27 |
easily start/stop the mounts like: |
| 28 |
|
| 29 |
#!/sbin/runscript |
| 30 |
|
| 31 |
depend() { |
| 32 |
need localmount |
| 33 |
need bootmisc |
| 34 |
} |
| 35 |
|
| 36 |
start() { |
| 37 |
ebegin "Mounting chroot dirs" |
| 38 |
mount -o bind /dev /mnt/standalone/dev >/dev/null |
| 39 |
mount -o bind /dev/pts /mnt/standalone/dev/pts >/dev/null & |
| 40 |
mount -o bind /dev/shm /mnt/standalone/dev/shm >/dev/null & |
| 41 |
mount -o bind /proc /mnt/standalone/proc >/dev/null |
| 42 |
mount -o bind /proc/bus/usb /mnt/standalone/proc/bus/usb >/dev/null & |
| 43 |
mount -o bind /sys /mnt/standalone/sys >/dev/null & |
| 44 |
mount -o bind /tmp /mnt/standalone/tmp >/dev/null & |
| 45 |
mount -o bind /usr/portage /mnt/standalone/usr/portage/ >/dev/null & |
| 46 |
mount -o bind /usr/distfiles /mnt/standalone/usr/distfiles >/dev/null & |
| 47 |
eend $? "An error occured while attempting to mount chroot directories" |
| 48 |
ebegin "Copying chroot files" |
| 49 |
cp -pf /etc/resolv.conf /mnt/standalone/etc >/dev/null & |
| 50 |
cp -Ppf /etc/localtime /mnt/standalone/etc >/dev/null & |
| 51 |
eend $? "An error occured while attempting to copy chroot files." |
| 52 |
} |
| 53 |
|
| 54 |
stop() { |
| 55 |
ebegin "Unmounting chroot dirs" |
| 56 |
umount -f /mnt/standalone/dev/pts >/dev/null |
| 57 |
umount -f /mnt/standalone/dev/shm >/dev/null |
| 58 |
umount -f /mnt/standalone/dev >/dev/null & |
| 59 |
umount -f /mnt/standalone/proc/bus/usb >/dev/null |
| 60 |
umount -f /mnt/standalone/proc >/dev/null & |
| 61 |
umount -f /mnt/standalone/sys >/dev/null & |
| 62 |
umount -f /mnt/standalone/tmp >/dev/null & |
| 63 |
umount -f /mnt/standalone/usr/portage/ >/dev/null & |
| 64 |
umount -f /mnt/standalone/usr/distfiles/ >/dev/null & |
| 65 |
eend $? "An error occured while attempting to unmount chroot |
| 66 |
directories" |
| 67 |
} |
| 68 |
|
| 69 |
then in laptop: |
| 70 |
|
| 71 |
/etc/init.d/standalone start && |
| 72 |
linux64 chroot <standalone> /bin/bash |
| 73 |
or (if standalone is 32bit) |
| 74 |
linux32 chroot <standalone> /bin/bash |
| 75 |
|
| 76 |
then once inside the chroot update the environment like: |
| 77 |
cd && env-update && source /etc/profile && export PS1='(standalone) \W # ' |
| 78 |
|
| 79 |
Then update as normal (emerge -DNuv world) ...etc (*) |
| 80 |
|
| 81 |
Once finished, exit chroot and unmount: |
| 82 |
exit && /etc/init.d/standalone stop |
| 83 |
|
| 84 |
connect laptop (or external disk) to standalone and sync the filesystem |
| 85 |
back, but _taking_care_not_to_delete_directories_you_need_to_keep_ like |
| 86 |
/home/... |
| 87 |
|
| 88 |
eg, make a script like: |
| 89 |
|
| 90 |
#!/bin/bash |
| 91 |
( mount |grep standalone ) && /etc/init.d/standalone stop |
| 92 |
cd /mnt/standalone && \ |
| 93 |
rsync -aHvx --exclude lost+found --delete boot/ standalone:/boot/ && \ |
| 94 |
rsync -aHvx --exclude lost+found --delete bin/ standalone:/bin/ && \ |
| 95 |
rsync -aHvx --exclude lost+found --delete sbin/ standalone:/sbin/ && \ |
| 96 |
rsync -aHvx --exclude lost+found --delete usr/ standalone:/usr/ && \ |
| 97 |
rsync -aHvx --exclude lost+found --delete lib/ standalone:/lib/ && \ |
| 98 |
rsync -aHvx --exclude lost+found --delete mnt/ standalone:/mnt/ && \ |
| 99 |
rsync -aHvx --exclude lost+found --delete net/ standalone:/net/ && \ |
| 100 |
rsync -aHvx --exclude lost+found --delete misc/ standalone:/misc/ && \ |
| 101 |
rsync -aHvx --exclude lost+found --delete var/ standalone:/var/ && \ |
| 102 |
rsync -aHvx --exclude lost+found --delete media/ standalone:/media/ && \ |
| 103 |
rsync -aHvx --exclude lost+found --delete opt/ standalone:/opt/ && \ |
| 104 |
rsync -aHvx --exclude lost+found --delete etc/ standalone:/etc/ && \ |
| 105 |
rsync -aHvx --exclude lost+found --delete root/ standalone:/root/ && \ |
| 106 |
echo "ALL DONE" |
| 107 |
|
| 108 |
|
| 109 |
(*) OR maybe this is safer, once in chroot environment, fetch the needed |
| 110 |
distfiles only: |
| 111 |
emerge -DNuvf world |
| 112 |
then rsync the /usr/distfiles/ and portage dirs to the standalone's |
| 113 |
machine dirs, and build the packages (update) on standalone. |
| 114 |
And rsync the standalone fs to the <standalone> dir on laptop/disk when |
| 115 |
you want to update again. |
| 116 |
|
| 117 |
Hope you got the idea. ;) |
