Title:
mountall blocks boot
Status in “mountall” package in Ubuntu:
Incomplete
Bug description:
after upgrading to Quantal the system no longer boots.
I've debugged the issue by booting with init=/bin/bash and it seems that mountall fails to spawn a few processes because PATH is wrong.
Here is the strace output:
[pid 3302] execve("swapon", ["swapon", "/dev/sda2"], [/* 9 vars */]) = -1 ENOENT (No such file or directory)
[pid 3302] execve("/bin/swapon", ["swapon", "/dev/sda2"], [/* 9 vars */]) = -1 ENOENT (No such file or directory)
[pid 3302] execve("/usr/bin/swapon", ["swapon", "/dev/sda2"], [/* 9 vars */]) = -1 ENOENT (No such file or directory)
[pid 3302] write(2, "mountall: swapon /dev/sda2 [3302"..., 61mountall: swapon /dev/sda2 [3302]: No such file or directory
) = 61
[pid 3302] write(15, "!", 1) = 1
[pid 3277] <... read resumed> "!", 1) = 1
[pid 3277] close(14) = 0
[pid 3302] exit_group(0) = ?
here mountall fails to spawn swapon, but the same happens to fsck.
