Binary package hint: autofs

Autofs fails to mount a remote file system if the remote path contains a space.
On the remote NFS server, syslog reports that it can't stat exported dir and
then prints the requested remote path ending at (before) the space. There is
no way to use autofs to mount a remote directory containing a space through any
combination of quoting or escaping. Using command-line "mount" command works
fine when the remote path is quoted. Autofs calls the "mount" command for the
actual mounting operation, so the problem is in autofs's preparation of the
remote path argument to "mount".
Cause: in autofs source file mount_nfs.c, in function get_best_mount(),
remote path is copied until space or end of string. If the remote path
contains a space, the string is terminated before the space. This
shortened string is then passed to the "mount" program as the remote
path to be mounted on the local mount point.
To duplicate:
1) Export a file system on the remote system, and make a directory underneath
the top level of the exported file system that contains a space. Example:
remote% cat /etc/exports
/export
remote% mkdir "/export/data/path with space"
2) On the local system, set up an automount map that maps to the remote
file system, and start autofs. Mount map example:
local% cat /etc/auto.master
/data /etc/auto.data defaults,intr
local%cat /etc/auto.data
* remote:/export/data/&
3) Attempt to access the local path:
local% ls "/data/path with space"
/bin/ls: cannot access /data/path with space: No such file or directory
On the remote machine's syslog:
Dec 8 16:25:24 remote nss_wins[801]: can't stat exported dir
/export/data/path: No such file or directory
