Hello,
I investigated a bit and found the issue, which probably explains quite
a few other bugs:
- I added fprintf(stderr,"%s:%s", __FILE__, __func__); fflush(stderr);
basically in all EBUSY places in libdiskfs, libnetfs, libfshelp
- I got it from libnetfs/netfs_S_file_set_translator.
That di

I do put printfs to stderr in my installed translators essentially all
the time, including ext2fs and such. So yes, th

I like to use error (0, 0, "didum"). It's easy to use, prints the
servers name, prints a newline and does fflush. The most annoying
thing about it is that it doesn't print the messa
BTW, one way to check what is actually getting run is using gdb:

Nothing wrong, except that you must be sure that the translator
can write to it. Making the root translator write to its own
/tmp/foobar.log is probably deemed to fail, for instance.

Nothing gets restarted when you install. Only the newer translator that
you start will use the new implementation.

Everything gets restarted of course.
Hi,
Attached is a partial summery trying to debug the problems with
fakeroot-hurd when building glibc.
Print statements to file are added to:
trans/fakeroot.c
libnetfs/file-set-translator.c
libdiskfs/file-set-trans.c
(and other files in libnetfs/, libdiskfs/, but no hits whatsoever for
them).
