Thanks everyone, I've nailed it \o/ A more detailed story follows. |
| 2 |
|
| 3 |
After taking the approach of offloading / and /usr checks to Dracut I've |
| 4 |
disabled fsck for those partitions in /etc/fstab so OpenRC fsck wouldn't |
| 5 |
attempt to check /usr (and fail) by setting passno (the last column to |
| 6 |
0). It turned out that Dracut honours fstab for fsck too (root get |
| 7 |
special treatment and is checked anyways). After enabling fsck in fstab |
| 8 |
for / and /usr Dracut started to check /usr - a small win already. No |
| 9 |
the only thing left to do was to _not_ check / and /usr by the init fsck |
| 10 |
which was natural to do by setting fsck_passno=">1" in /etc/conf.d/fsck. |
| 11 |
|
| 12 |
Now all the filesystems are checked during the boot: the ones having |
| 13 |
passno 1 (root and /usr) by the initramfs and passno 2 (/var, /home, |
| 14 |
/data) by the init. The relevant excerpts from the final configuration |
| 15 |
are below. |
| 16 |
|
| 17 |
/etc/fstab: |
| 18 |
/dev/MacVg/gentoo-root / ext4 defaults 0 1 |
| 19 |
/dev/MacVg/gentoo-usr /usr ext4 defaults 0 1 |
| 20 |
/dev/MacVg/gentoo-var /var ext4 nodev,nosuid 0 2 |
| 21 |
/dev/MacVg/gentoo-home /home ext4 nodev,nosuid 0 2 |
| 22 |
/dev/MacVg/data /data ext4 nodev,nosuid,noexec 0 2 |
| 23 |
|
| 24 |
/etc/dracut.conf: |
| 25 |
hostonly="yes" |
| 26 |
use_fstab="yes" |
| 27 |
no_fsck="no" |
| 28 |
|
| 29 |
Note that the two latter Dracut options are not required and applied by |
| 30 |
default in my installation but showing explicitly what configuration is |
| 31 |
used. |
| 32 |
|
| 33 |
/etc/conf.d/fsck: |
| 34 |
fsck_passno=">1" |
| 35 |
|
| 36 |
As can be seen from logs / and /usr are checked by Dracut and /var, |
| 37 |
/home and /data by OpenRC. |

P. S. A bonus point is I no longer have to patch genkernel to support |
| 83 |
custom keymaps and fonts. |
