By the way, since you've mentioned that, we've been thinking about
some options for configuration file for quite some time (not only for
custom group generation, but also for color output configuration, lua
invasiveness and other not-yet-merged stuff). Does anyone have any
ideas regarding a good configuration file syntax?
The other question is about prefix for user-configurable groups, it
probably shouldn't conflict with any existing syscall qualification
syntax, but, for example, "%%%" looks too unwieldy.

Re: GSOC:Microproject
How about allowing a user to define ones' own class in ~/.strace?
(cat ~/.strace)
classes:
- name: xattr
- syscall: setxattr
- syscall: lsetxattr
- syscall: fsetxattr
- syscall: getxattr
- syscall: listxattr
- syscall: removexattr
- name: setxattr
- syscall: setxattr
- syscall: lsetxattr
- syscall: fsetxattr
So you can do -e trace=%xattr or -e traec=%setxattr as you want.
However, I think we cannot say thie extension a microproject:-P

This is a good start, but from what I see, maybe this group is too
small, maybe all the syscalls that deals with xattr should be a better
idea, something like -e trace=%xattr.

Doesn't -e trace='/[lf]?setxattr' cover precisely this set of syscalls
on any architecture?

I have grouped all xattr syscalls and following is attached patch for the
same. Please review.
