[Bug 2027979] [NEW] won't warn neither prevent usage of « risky » characters in labels

[Coeur Noir]

Public bug reported:

Hi,

if naming or renaming an EXT volume,

e2label lets you use any character, including / or * or $ ( and probably
others )

I'd expect at least a warning if such are to be found in a label name.

Or better, it should not be possible to use those in label names.


Example :

a at p:~$ sudo e2label /dev/sdb12 /Ti\$*
a at p:~$ 

a at p:~$ sudo e2label /dev/sdb12
/Ti$*
a at p:~$ 

a at p:~$ lsblk -fe7 | grep sdb12
└─sdb12   ext4              1.0   /Ti$*             f583e9b0-f1de-438f-8da8-c1e070407628                
a at p:~$
