but that will only happen if you changed from, say, 2.6.24 to 2.6.26.

if just the git rev changed such as
a1e97c611253511ffc2d8c45e3e6d6894fa03fa3 to
6e2a723ef54ee2e739c34786981b2c508db803c1

then opkg wouldn't know about it.

my problem looks like this:


root at om-gta02:~# opkg status kernel-module-xt-physdev
Package: kernel-module-xt-physdev
Version: 2:2.6.24+git75969+a1e97c611253511ffc2d8c45e3e6d6894fa03fa3-r1.01
Depends: update-modules, kernel-2.6.24, kernel-module-x-tables
Status: install ok installed
Architecture: neo1973
Installed-Time: 1226894980

root at om-gta02:~# opkg status kernel-module-xt-tcpudp
Package: kernel-module-xt-tcpudp
Version: 3:2.6.24+gitr1+6e2a723ef54ee2e739c34786981b2c508db803c1-r2
Depends: update-modules, kernel-2.6.24, kernel-module-x-tables
Status: install user installed
Architecture: om-gta02


these 2 packages coexist on the same rootfs after opkg upgrade.
