the release of the distribution , built on a package base and supplemented with tools aimed at use in scientific institutions.
Distribution for x86_64 architecture, in the form of DVD images (9.8 GB and 8 GB), a minimal image for network installation (496 MB). The release of Live images is postponed.
The differences from RHEL mainly come down to rebranding and cleaning up ties to Red Hat services. Applications specific to scientific use, as well as additional drivers, are offered for installation from external repositories such as and .
Key Scientific Linux 7.7:
- Added packages with Python 3.6 (earlier Python 3 was not included in RHEL);
- Added a package with , an open implementation of the Andrew File System distributed file system;
- Added the SL_gdm_no_user_list package, which disables the display of the user list in GDM when a stricter security policy is required;
- Added the SL_enable_serialconsole package for configuring a console operating via a serial port;
- Added the SL_no_colorls package, which disables colored output in ls;
- Changes have been made to packages, mainly related to rebranding: anaconda, dhcp, grub2, httpd, ipa, kernel, libreport, PackageKit, pesign, plymouth, redhat-rpm-config, shim, yum, cockpit;
- Compared to the Scientific Linux 6.x branch, the base set is missing packages alpine, SL_desktop_tweaks, SL_password_for_singleuser, yum-autoupdate, yum-conf-adobe, thunderbird (available in the EPEL7 repository).
- Components (shim, grub2, Linux kernel) used for booting in UEFI Secure Boot mode are signed with the Scientific Linux key, which requires performing , as the key needs to be added to the firmware;
- For automatic updates, the yum-cron system is used instead of yum-autoupdate. By default, updates are applied automatically with subsequent notification sent to the user. To change the behavior at the automated installation stage, packages SL_yum-cron_no_automated_apply_updates (which prohibits automatic installation of updates) and SL_yum-cron_no_default_excludes (which allows updates to the kernel) have been prepared;
- Configuration files for external repositories (EPEL, ELRepo,
SL-Extras, SL-SoftwareCollections, ZFSonLinux have been moved to a centralized repository since these repositories are not specific to particular releases and can be used with any version of Scientific Linux 7. To load repository data, run "yum install yum-conf-repos" and then configure individual repositories, for example, "yum install yum-conf-epel yum-conf-zfsonlinux yum-conf-softwarecollections yum-conf-hc yum-conf-extras yum-conf-elrepo."
