Disabling prelink in software builds

2011-05-17 Thread Daniel Drake
Hi, Currently, olpc-os-builder prelinks the whole filesystem during the build process. Unfortunately this is causing olpc-update to do lots of work, as even when you prelink the same binary twice, the output changes, e.g.: [root@dsdfedora bin]# prelink -u /usr/lib/libxml2.so.2 [root@dsdfedora

Re: Disabling prelink in software builds

2011-05-17 Thread John Gilmore
Any objections to prelink being disabled? I object. You are running a diskless, swapless system. The whole point of prelink is to make your read-only binaries actually remain read-only, rather than requiring the dynamic linker to modify them in memory. This allows large numbers of pages of

Why not remove or normalise the timestamp in the prelink output? I made a local version of prelink that avoided the use of time(2) in setting the timestamp, and then compared the result against the system version or prelink: # prelink -u /tmp/libxml2.so # prelink /tmp/libxml2.so # md5sum
