Public bug reported:
If the mount option "timeo" is specified for an NFS mount in /etc/fstab,
mountall does not pass it to mount.nfs. The bug is in the function
cut_options() in mountall.c. It is called with the following arguments:
opts = cut_options (NULL, mnt, "showthrough", "optional",
"bootwait", "nobootwait", "timeout",
NULL);
Although it should only remove the specified options, it also removes
any option that is a prefix of one of those, e.g. "timeo".
The call to strncmp() in line 661 compares only up to the length of the
option from the fstab, without comparing the length of both strings.
Hence I propose the following patch:
--- mountall-2.36/src/mountall.c.orig 2012-08-24 20:25:07.445892095 +0200
+++ mountall-2.36/src/mountall.c 2012-08-24 21:29:10.098595843 +0200
