Subject: [PATCH] fsck: look for fsck binary not just in /sbin
|
|
|
|
This removes remaining hardcoded occurences of `/sbin/fsck`, and instead
|
|
uses `find_executable` to find `fsck`.
|
|
|
|
We also use `fsck_exists_for_fstype` to check for the `fsck.*`
|
|
executable, which also checks in `$PATH`, so it's fair to assume fsck
|
|
itself is also available.
