Status of systemtap in Debian
[ M-F-T set to debian-devel@ ]
Systemtap is a tool allowing to dynamically insert probes in the
Linux kernel, similarly to what is possible with DTrace on Solaris.
The state of systemtap in Debian is currently worrying. First, the
package has been orphaned (#568866). I'm willing to take over
maintenance, but there's another, bigger problem: the Debian kernels
don't provide debuginfo, so they are unsuitable for use with systemtap.
Users are required to build a custom kernel.
This has been discussed at length in #365349, and the blockers are:
- disk space on buildds: at least 2 GiB are required to build a kernel
with debuginfo. (that doesn't sound too hard to satisfy)
- mirror space: each debug .deb would use ~ 450 MB (see
Debian is currently the only major distro where users are required to
build their own kernel to use systemtap, so I think that we should try
to support it, at least for some kernel flavors and some
Kernel, buildd and mirror people, what do you think?
