Would a small module implementing <fstab.h> be accepted upstream into
musl? I looked on the mailing list and wiki and didn't see anyone
asking this question before.
This header and API are used by at least:
- filelight (disk space usage tracker)
- K3b (KDE disc ripper)
- KDELibs 3.x, used by TDE (Trinity Desktop Environment, light Qt DE)
- MythTV and XBMC (media center/players)
- Pegasus (scientific computation management system by USC)
Since this is already implemented by glibc[1], FreeBSD[2], NetBSD[3],
OpenBSD[4], Mac OS X[5], AIX[6], HP-UX[7], QNX[8], and
others[9][10][11][12], all but TDE's fork of KDELibs 3 don't check for
it in configure. I would be more than happy to implement and maintain this.
Best,

Seems plausible that it would be reasonable but I haven't looked at
the specifics. How large would the implementation be? Are there ugly
issues with thread-safety/global state that make the apis hard to use
reasonably? Anything weird it has to hook into?

they dont look like being thread safe or async safe atleast in glibc
docs. perhaps you can use gnulib
implementation in apps where its needed.

Add XFCE 4 to this list: their disk monitor panel plugin requires
<fstab.h> and does not test for it in configure since it is so widely
implemented (as below).

It's basically the /etc/fstab equivalent of <mntent.h>. It has the same
considerations as <mntent.h>. It's MT-unsafe and AS-unsafe because it
does the set/get/end ent stuff, just with /etc/fstab instead of
/etc/mtab (or /etc/passwd in the case of pwent, etc).
https://www.gnu.org/software/libc/manual/html_node/fstab.html is the
glibc manual for it.
I will likely write a basic implementation up next week, and send it to
the list.
Best,
