The following reply was made to PR kern/118170; it has been noted by GNATS. From: Jaakko Heinonen <jh@saunalahti.fi> To: kmacy@FreeBSD.org Cc: koie@suri.co.jp, bug-followup@FreeBSD.org Subject: Re: kern/118170: [zfs] /bin/pwd fails under .zfs/snapshot Date: Fri, 29 May 2009 16:58:50 +0300 Hi, On 2009-05-28, kmacy@FreeBSD.org wrote: > no longer applies > > kmacy@delirium [/usr/.zfs/snapshot|16:09|109] cd foo > kmacy@delirium [/usr/.zfs/snapshot/foo|16:09|110] pwd > /usr/.zfs/snapshot/foo The problem still exists. It seems that you used shell built-in pwd which doesn't call getcwd(3) but uses it's own bookkeeping for working directory. The problem was discussed on -fs in February and I described it in this message: http://lists.freebsd.org/pipermail/freebsd-fs/2009-February/005671.html Since then __getcwd() has improved because vop_stdvptocnp() can now use readdir("..") to resolve component names. However it can't cross mount points and because zfs snapshot are mounted the problem is still there. -- Jaakko
