Hi
this is a follow up to another thread called "Unclear sstate-cache dir
permissions"
I am trying to share a sstate-cache between two (or more) users in a
shared directory.
Although I set the directory owner, group and permissions I face to a
weird condition that I don't understand and seems to point out a
bitbake/class problem.
Problem description
I have a shared area with the following permissions (g+ws) set up at
before the builds
ls -al /opt/yocto
drwxrwsrwx 4 tux yocto 20480 set 28 14:47 downloads
drwxrwsrwx 259 tux yocto 4096 set 28 15:33 sstate-cache
This is the common local.conf
DL_DIR ?= "/opt/yocto/downloads"
SSTATE_DIR ?= "/opt/yocto/sstate-cache"
1. workspace1 with user1 (tux) generates the first build
using bitbake core-image-minimal
/opt/yocto/sstate-cache (content excerpt)
drwxr-xr-x 2 tux yocto 4096 set 28 14:44 94
drwxr-sr-x 2 tux yocto 4096 set 28 14:45 95
drwxr-xr-x 2 tux yocto 4096 set 28 14:46 96
2. build on workspace2 using user2 (devel) faces to the following problem
Permission denied: '/opt/yocto/sstate-cache/95/sigtask'
because the permissions of directory '95' is 'drwxr-sr-x'
$ bitbake core-image-minimal
