DPKG BUILD PROFILES =================== There are some custom build profiles that are disabled by default: pkg.swupdate.bpo Build a backport friendly version of the package with some default features disabled that would require unavailable dependencies. Currently this targets bullseye. pkg.swupdate.p11 Enable using PKCS#11 for AES decryption instead of having the plain key available in a file. pkg.swupdate.nohwcompat Disable the comparison with the hardware compatibility file /etc/hwrevision. pkg.swupdate.nosigning Disable Cryptographic Message Syntax (CMS) signature verification on SWU files. Cryptographic hash verification (integrity) is still enabled with this set. Please only use this when you can ensure authenticity in some other way. pkg.swupdate.noswuforwarder Disable the SWU forwarder. This gets rid of the libwebsockets dependency. EXAMPLES ======== /usr/share/doc/swupdate/examples/udev holds an example on how to make SWUpdate trigger installing updates on inserting USB flash drives with SWU files on them.
