linuxrc: do not rely on chroot evaluating PATH |
| 9 |
|
| 10 |
When trying to install a new kernel on catbus.sparc.dev.gentoo.org, the |
| 11 |
newly built initrd consistently claimed that it could not find init, and |
| 12 |
dropped to the rescue shell. |
| 13 |
|
| 14 |
However, init was there just fine in /newroot (as before). |
| 15 |
|
| 16 |
I dug out the command that is actually run inside linuxrc, |
| 17 |
|
| 18 |
elif ! chroot "${CHROOT}" test -x /${init#/} 1>/dev/null 2>&1 |
| 19 |
|
| 20 |
and tried to run that manually, which led to a rather strange error message |
| 21 |
|
| 22 |
rescueshell / # chroot /newroot test -x /lib/systemd/systemd |
| 23 |
chroot: can't execute 'test': File name too long |
| 24 |
|
| 25 |
Some more research led me to the busybox manpage (where here chroot comes |
| 26 |
from): |
| 27 |
https://busybox.net/downloads/BusyBox.html#chroot |
| 28 |
|
| 29 |
chroot |
| 30 |
chroot NEWROOT [PROG [ARGS]] |
| 31 |
Run PROG with root directory set to NEWROOT |
| 32 |
|
| 33 |
Note, the third argument is *not* a command (as with usual chroot, see the |
| 34 |
manpage from coreutils chroot) but a program! |
