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

[Coeur Noir]

Ok, ok, amen, so be it.

If it's ok in fstab, if bash always expands correctly then you're right,
don't change anything if it would bring more annoyance than ease of
life.

Title is « won't warn neither prevent usage of « risky » characters in labels »
Nothing else.

Accented letters in partition label seem ( nowadays ) a problem with
latest Ubuntu installer - as reported by geole on the forum ( am just
quoting here as I was unable to do anything with the latest Ubuntu
installer by my side, so can't confirm myself. )

No backpedaling from me - your bad reading because you jumped on
accented letters while I always was worrying about the « special / risky
» characters and insisted twice on that matter.

« Why should we print some kind of nanny-state, "naughty, naughty! you did something that might confuse a less clueful user!!" warning »
Because that's how you catch attention on a topic and eventually teach someone how to do better, for self and others.

Anyway thank you for your answers and explanations which justify why e2label needs no change.
Labels can't be an issue if I understand correctly. 

( oot : foolproof is the first translation I've found for « à toute
épreuve » ; bulletproof ? )

Title:
  won't warn neither prevent usage of « risky » characters in labels

Status in e2fsprogs package in Ubuntu:
  Confirmed

Bug description:
  Hi,

  if naming or renaming an EXT volume,

  e2label lets you use any character, including / or * or $ ( and
  probably others, like accented letters é è à )

  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$*             f583e9b0-f1de-438f-8da8-c1e070407628
  a at p:~$
