rpmrebuild is a tool to build an rpm file from the rpm database
of installed softwares.
It can be used to quickly build modified rpm packages.
how does it work
The rpm database contains many things,in fact all what is need to build the rpm file
(even the pre/post install scripts).
One can access the database in shell-script (rpm -q), or throw an API in C language.
I choose the shell-script for portability, debug facility, and because there was no
- the rebuild is done from the installed files, so, if there was some
modifications (config or so), they are reported in the new package.
but I show what is concerned
- if the original package was signed, the new one is not
last remark :
the rpm software as now a "repackage" option but :
- it is not documented in man page
- it can only be used in erase command (rpm -e --repackage), this can be not possible because of dependencies
- for informations, the result goes to /var/spool/up2date
The script as only been tested on redhat distribution (6.x and 7.x releases)
but should work on any distribution now.
In 1999, I had a big problem, when updating a package : the new version was not working !
So I had to "go back", but it was impossible to find the old rpm file (on local disk, or on the net).
I just had it installed, on another host ...
I do not find any tool on the net, so I write a first release for this need, and I use it rarely.
But, in July 2002, I had a request from other Linux admin.
As the script seems to match a more general need, I decide to put public on the net
