--autosysroot option uses suggestions to user on how to mount filesystems and change root suggested by --suggest option in virt-rescue. Commands are passed on kernel command line in format guestfs_command=command;. Command ends with a semicolon and there can be multiple commands specified. These are executed just before bash starts. On successfull run user is presented directly with bash in

...and then use a sequence of Xs of the same length as input to the underlying C printf to determine the amount of leading and trailing padding. Finally we replace the Xs with the actual string before writing it out. In order to print out the temporary string containing Xs and padding, a new helper xasprintf is added. Unlike asprintf though, our xasprintf prints to the ash stack rather than using straight malloc memory.

Hello, With the introduction of SSH_ASKPASS_REQUIRE in version 8.4, I've set up a script for SSH_ASKPASS to query my local passwordstore (https://www.passwordstore.org/) vault to retrieve the password for a given key. This works for ssh-add as well as ssh (configured with AddKeysToAgent set to 'yes'). My workflow effectively transforms into entering the password for the GPG key used

https://bugzilla.mindrot.org/show_bug.cgi?id=2561 Bug ID: 2561 Summary: ssh-keygen -A does not recreate broken zero-sized host keys Product: Portable OpenSSH Version: 7.2p1 Hardware: All OS: All Status: NEW Severity: normal Priority: P5 Component: ssh-keygen
