 Hi Joerg,
 
 My use case is for this issue[1].  For sudo it'll be easier to search
 the problem with "-Wl,-zrelro" flag without a big enough page size.
 And it'll help with the gnupg2 issue more.  If you check the build log
 I attached in [2], one of the utilities it built ended up in
 segmentation fault but didn't fail the build process, and the produced
 gpg2 program will segfault in runtime randomly too.  Because I built
 it using pbulk which didn't support keeping logs for successful
 packages and used a different prefix for all its builds, I had to
 rebuild everything in the pkgsrc tree to get this build log, and given
 Loongson being a 15+ year machine which wasn't even performant back
 then, it took me another whole day to build all the dependencies of
 gnupg2 to get this log.  It would be much easier if pbulk can just
 keep the build log for helping debugging runtime issues like this.
 
 As for the space concern, what I'm suggesting here is just to keep the
 build logs, and it's really not much compared with size of a work
 directory which pbulk already supports to keep by the "keep_wrkdir"
 options, so I wouldn't worry too much, especially when this is turned
 off by default.  Actually, I may take a step further by gzipping all
 the build logs to save more spaces if desired.
