I encountered the existence of a file named
bootstrap.log in the
/var/log directory when trying to solve a log related problem and when looking at its content I saw that the timestamps are over a year old.
It seems to be consisting of a lot FTP-links, dpkg-warnings like "ignoring pre-dependency problem!" and information concerning unpacking .deb-packages, which seems to be pointing to installation related data.
To see if a relation existed with the installation date I did:
$ ls -lt /var/log/installer total 752 -rw-r--r-- 1 root root 387038 dec 17 2022 initial-status.gz -rw------- 1 root root 277005 dec 17 2022 syslog -rw------- 1 root root 1509 dec 17 2022 casper.log -rw-r--r-- 1 root root 64 dec 17 2022 media-info -rw------- 1 root root 91778 dec 17 2022 debug
From which I conclude that the installation took place at dec 17, 2022.
The timestamped entries in bootstrap.log all start with 2022-08-09, so this would be before the installation.
I searched for information on bootstrap.log, but could not find enlightening information on the subject.
This made me wonder what exactly the of use
bootstrap.log is, why it has been created and if its content will change at all after its original creation date.
I am on Ubuntu 20.04.3
