Yes that sounds good. > Since the <bits/syscall.h> (included through <sys/syscall.h>) > header is generated automatically from the kernel headers at glibc > build time, Debian should make sure that the latest available > kernel headers are used, so building the latest Sid glibc package > should be done on a system with also the latest kernel available > in Sid, to have a complete SYS_xxx list. This is basically what is done, the buildd chroots are updated twice a week, so in the worst case glibc is build against a kernel headers package that is 4 days old.
