Package: autofs
Version: 5.1.2-1
Severity: important
Hi,
Since stretch update, there is no way to automount a smb share with a '$' at
the end of its name anymore. But these names are automaticcaly generated by
windows when the share is hidden by default...
The auto.smb script has a awk script to protect the '$' character.
It works for the local mount path and options (cf user='...' parameter below),
but not for the server path.
# /etc/auto.smb nas-stbm
-fstype=cifs,multiuser,cruid=0,sec=krb5,user="HOSTNAME\$" \
"/GENOME$" "://nas-stbm/GENOME\$" \
[...]
I tweak /etc/auto.smb to get the options I wanted. But I tried
to generate both version (quoted or not) :
A: "/GENOME$" "://nas-stbm/GENOME\$"
B: "/GENOME$" "://nas-stbm/GENOME$"
Both fails.
Running autofs in debug mode, for A, I got:

I workaround the problem by renaming /sbin/mount.cifs into mount.cifs.real
and writing the following script in /sbin/mount.cifs:
#!/bin/bash
SHARE="${1/\\\$/\$}"
shift
exec "$0".real "$SHARE" "$@"
Please, propose a way (whatever it is) to quote the share name.
Regards,
Vincent
