Re: [opensuse-factory] Re: [PLEASE SPEAK UP] Disabling legacy file systems by default?
Hi Jeff- have data been gathered regarding these file systems which the
"vast majority of users" use? If so, where might I find these data?
Does SUSE or anyone else gather these data regarding users of
(open)SUSE? If so, how are these data gathered?


Best, Jim

Hi Jim- so far as I'm aware, thinking does not necessarily match
reality. I couldn't tell you how many attend that conference, but I

wonder what a representative sample of (open)SUSE users would
report as
"necessary" file systems. Without such a sample this proposed
change
appears quite reckless.

I don't have a horse in this race, but going to the site for the
Berlin
2018 conference doesn't make me think that this affects thousands
of
users. It makes me think it affects about 20. Small conference
rooms, a
relatively small lunch gathering. Makes me wonder what the
actual
attendance is.

The solution is simple - remove the filesystem from the
blacklist. Seems
like a really easy thing to do for something that's used by 20
people.

It's not like the filesystem module is not being built or
included.

In terms of local file systems, the vast majority of users use:
ext2/3/4, xfs, btrfs, and reiserfs[1]. OCFS2 and GFS2 are common
enough
that I wouldn't want to blacklist them. JFS saw some use in the past
but it was never particularly popular since it was the disk format
used
by OS/2 and not the AIX version. My opinions on it aren't
new[2]. The
rest are for compatibility with now-ancient or otherwise uncommon
OSes,
for pure flash (ie: without an FTL) media, or have other maintenance
issues (f2fs). Are there users out there for any of these? I'm sure
there are a handful. I just don't think it's worth leaving the
attack
surface open for the vast majority of users to accommodate a few --
especially if we can minimize the impact on the few.

Now that I look at it again, the list was composed using the file
systems we build on SLE15. There are two others that should be
added:
omfs
ntfs[3]

[1] I expect this will go on the blacklist at some point in the
future
as I'm the last person to do any real work on it and I have other
priorities that take precedence.

-- I'm assuming the staff member was me in this case. Dave also says
that he tries to fix bugs but the hard ones go unfixed. This was 11
years ago.
[3] Not that NTFS isn't widely used; Just that the only attention
that
the ntfs kernel module has has seen since 2007 has been for tree-wide
cleanups and API changes. Use ntfs-3g instead.
