Hello,
I'm both reporting a bug and submitting a patch, so hopefully it's
okay I used lfs-dev instead of the lfs-patches mail list?
If the virtual filesystems are not listed in /etc/fstab the
mountvirtfs boot script fails with the following error:
Mounting virtual file systems: /run
/procmount: /proc: mount failed: No such file or directory
/sysmount: /sys: mount failed: No such file or directory
***** [ FAIL ]
***** [ FAIL ]
FAILURE:
You should not be reading this error message.
It means that an unforeseen error took place in
/etc/rc.d/rcS.d/S00mountvirtfs,
which exited with a return value of 1.
If you're able to track this error down to a bug in one of
the files provided by the files provided by
the LFS book, please be so kind to inform us at
lfs-...@linuxfromscratch.org (Registration required).
***** [ FAIL ]
Since not listing virtual filesystems in /etc/fstab is considered
acceptable (even recommended) on modern Linux installations [1][2][3],
the mountvirtfs script should correctly handle this situation.
The fix is pretty trivial: the mount commands in mountvirtfs simply
need to specify the virtual filesystem type and device.
I've attached patches for both the lfs 7.5 stable and lfs dev versions
of the bootscripts package.
Cheers,
Dylan
